SPRING EDHBOTTOV.

SPECIFICATION forming part of Letters Patent No. 392,755, dated November 13, 1888.

Application tiled December 20, 1887. Serial No. 258,434.

. able to suit bedsteads of dili'erent sizes and to enable it to be folded into compact form for storage or transportation. An additional olojeet is to cause the connected springs to yield readily to the expansion or contraction of the bed-bottom, while always forming a continuous bearing-surface for the support of the bedding.

rlhe invention consists in the peculiar construction and arrangement of parts, as hereinafter fully described, and pointed out in the claims.

In order that my invention may be fully understood, I will give a more detailed description of the construction and use of the same.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the iigures.

Figure l is a plan View of an adjustable spring bed-bottom embodying my invention. Fig. 2 is an enlarged plan View of a portion of the saine. Fig. 3 is a cross-sectional elevation on the line .fr a, Fig. 2, and Fig. 4 is a reduced inverted plan view of one end of the bed-bottoni when folded.

Upon each of the slats A, which are here shown ruiming lengthwise of the bed-bottom, are fixed a series of equidistant coiled springs, B, in any ordinary or approved manner.

The under sides of all the slats A are pivotally connected near either end to and by lazy-tongs C, which allow the slats carrying the springs to be separated to any desired degree according to the size of the bedstead to which the bed-bottom is to be applied, or to be folded closely together, as shown in Fig. a, for convenient storage or removal, while (Model.)

causing the slats to always maintain their equidistant relation with each other.

In order that the springs may afford a conthose on the two outside slats and one-half of the end springs, is passed from the under side around'the upper coil, B2, ofthe laterally-adjoining spring on the next adjacent slat, and then carried to and looped securely over the upper coil of the longitudinally-adjoining spring on the same slat.

The order of connection is reversed on the two halves of the bed-bottom, as shown in Fig. l, the terminal springs on opposite ends of the two halves having their 'upper ends just outside their connection with the longitudinally-preceding springs bent inward and fastened to their own second coils.. The ends of the two outside series of springs are carried around and soldered or otherwise firmly attached to longitudinal stiffeningestrips E before being looped to the respective succeeding springs.

The springs, being thus loosely connected laterally, accommodate themselves to the lateral adjustment of the slats, while being connected securely lengthwise they form always a continuous sustaining-surface.

Having thus `fully described my invention, I claim as new and desire to secure by Letters Patent- 1. An expansible spring bedebottom con'- sisting of a series of slats adjustably secured together and a series of coiled springs secured to the slats and having their upper ends passed under and around the upper coil of the spring on the adjacent slat and then loosely connected to the spring on the same slat, substantially as described.

2. The herein-described eXpansible spring bed bottom, consisting of the longitudinal slats A, the lazy-tongs C, connecting the said slats, and the coiled springs B, secured to the slats and havingtheir upper ends passed under and around the upper coil of the spring on the adjacent slat, and then looped around the adjacent spring on the same slat, as specified.
